Treatment Option OverviewRevised text to state that prospective, randomized, controlled trials with both agents have not shown an increase in overall survival (OS) when compared with observation (cited Kirkwood et al. and Eggermont et al. as references 9 and 10, respectively.) Also added text about therapies that have impacted OS in patients with recurrent or metastatic disease that are now being tested as adjuvant therapy in clinical trials, including

Cancerprevention is action taken to lower the chance of getting cancer. By preventing cancer,the number of new cases of cancer in a group or population is lowered. Hopefully,this will lower the number of deaths caused by cancer. To prevent new cancers from starting,scientists look at risk factors and protective factors. Anything that increases your chance of developing cancer is called a ...
Avoiding risk factors and increasing protective factors may help prevent cancer.Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking, eating a healthy diet, and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer.Being exposed to ultraviolet radiation is a risk factor for skin cancer.Some studies suggest that being exposed to ultraviolet (UV) radiation and the sensitivity of a person's skin to UV radiation are risk factors for skin cancer. UV radiation is the name for the invisible rays that are part of the energy that comes from the sun. Sunlamps and tanning beds also give off UV radiation.Risk factors for nonmelanoma and melanoma cancers are not the same.Risk factors for nonmelanoma skin cancer:Being exposed to natural sunlight or artificial
Tumor SizeUveal melanoma most often assumes a nodular or dome-shaped configuration, but occasionally tumors can be flat or diffuse and involve extensive areas of the uvea with little elevation. Tumor size classifications according to boundary lines used in a Collaborative Ocular Melanoma Study (COMS) are as follows: Small: Range from 1.0 mm to 3.0 mm in apical height and largest basal diameter of 5.0 to 16.0 mm. Medium: Range from 3.1 to 8.0 mm in apical height and a basal diameter of not more than 16.0 mm. Large: Greater than 8.0 mm in apical height or a basal diameter more than 16.0 mm, when the apical height is at least 2.0 mm.Although most ocular melanomas have a raised configuration, about 5% grow in a diffuse pattern that also may have prognostic significance. The tumors have a horizontal, flat-growth pattern, with the thickness measuring approximately 20% or less than the greatest basal dimension. This uncommon variant of uveal

There are different types of treatments for patients with intraocular melanoma. Different types of treatments are available for patients with intraocular melanoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.Five types of standard treatment are used:SurgerySurgery is the most common treatment for intraocular melanoma. The following types of surgery may be used:Resection: Surgery to remove the tumor and a small amount of healthy tissue around it.Enucleation: Surgery to remove the eye and part of
About PDQPhysician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government's center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.Purpose of This SummaryThis PDQ cancer information summary has current
